Off topic... but speaking of sync. This person has been up to! Compute module supports IEEE1588.

github.com/raspberrypi/linux/pull/5002/c...d95f7a1e64dd6d06ab7#

github.com/raspberrypi/linux/pull/5002

"Test & Performance:
We have tested the features in our lab and are able as a client to run at -7 intervals without significant performance impact. We are able to maintain synchronisation of the PHC within +/-10ns of its grandmaster PTP source and the system clock within 1-2us of the PHC."

How does that stack up against the EL6688 etc.

So if we want to deploy a file with our image, how do we do that?
Thinking of a .deb or wheel for vtk.

deb should be fine

if you have it hosted somewhere we can add a wget and dpkg-i into the uscripts file

Just about made a working "debian" fork of the full LXQT 1.1 source.  I imported the dsc files from a bleeding edge ubuntu ppa and fixed dependencies for bookworm. The workflow took a little figuring out!  Roughly speaking for 30+ packages...

Code:
cd package gbp import-dsc ../package.dsc --create-missing-branches gbp dch -S -a --debian-branch=$GBP_BRANCH && git commit --amend -C@{0} debian/changelog gbp buildpackage -us -uc --git-ignore-branch --git-ignore-new

I should have the sid deb packages for arm64 done by the end of the weekend.
>> github.com/djsftree/lxqt

Deps as I go...

elovalvo's method to install qtvcp did not work for me, At least the install script ran perfectly instead of erroring. I was getting segmentation faults with qtplasmac, and other sample screens did not load.
 

The problem is related to the installation of lxde.

As suggested in
github.com/gnome-pomodoro/gnome-pomodoro/issues/344

you have to add in /usr/share/dbus-1/services/
the file named

org.freedesktop.Notifications.service

containing this
Code:
[D-BUS Service] Name=org.freedesktop.Notifications Exec=/usr/lib/notification-daemon/notification-daemon

Excellent!, that did the trick!

ftree, we need to create
/usr/share/dbus-1/services/org.freedesktop.Notifications.service
with that content above

The QTPYVCP guys have been kind to us and have contributed a .deb file for vtk and a simple test file. Downloading the .deb file now. 477mb does not lend itself to being shared on the forum!

My little SSD filled up so I had to blow away all my vtk stuff except the wheel but it was looking for a missing module when I installed with pip.

So am stuck on vtk at the moment. Odd thing is I got it working once before.
I need to find some time on my work PC to rebuild the image and regroup...

Cool!  Do you have a link?  I'll give it a try.
